IMI-ROVED RAILWAY-CAR COUPLING.

Specification .forming part of Letters Patent No. 107,008, datedSeptember 6, 1870 antedated July 15, 1.870

I, RENSSELAEE A, COWELL, of Cleveland, 1n the countyof Cuyahoga andState of Ohio,

have invented certain Improvements in Caror bumper, formailwaycars,having suitable open spaces cast in the head for the reception ofthelink b,conp1ingpin c, and pallet d. The space or chamber a, in whichthe pin c plays,

is as long as the pin, and isl provided with a shoulder, c', upon whichthe head vof the pin rests, and below which it cannot pass. The top .otthe chamber a is covered with a cap, e, secured by a small bolt 'andnut, f. vThe cap c has a hole, b', through which a rod or chain, g,passes, attached to the eye of the pin. The cap e prevents the pin beingwithdrawn from lts chamber a, and, consequently cannot be misplaced orlost. Thepallet d is pivoted at d', and is operated by the link b. B isa rubber spring, through which the link bis passed,

leaving a suicient portion of the link projecting at either end to enterthe draw-head.

The face of the draw-head against which the spring B bears is not madeas `flaring as it usually is' in the ordinary draw-head, in order -togive the spring a better bearing, the linkentering just sufficient toallow the pin to drop through it into place. The link, when placed inone draw-head, by this means is held in a horizontal position, and isalways readyfand easily enters the opposite draw-head. v

A coil spring of steel, embracing the link b, s

may be used instead of the rubber, or an elli-ptic spring may bev usedinstead of therubber, for the same purpose, but I prefer the rubber, forthe reason that it is simpler, more readily applied, and not liable tobe broken or to get out of order. l

The use ofthe spring B is to keep the drawheads spread to the extent ofthe link, and to take up the jarring by the concussion of cars, thusrendering a train devoid of the annoyance of sudden jerking and jarringin starting and stopping trains. The spring yields sufficiently for carsrunning on a curve, and will also prevent cars jumpingthe track.

When the cars are to. be uncoupled, the 'pin cv is raised in'its chambera, and as soon as the .lin-k is withdrawn, the pallet d falls, and thepin rests upon it, ready to'be again coupled. The link, raising thepallet, lets the pin fall into place It will be seen that thechamberqc', in the lower side ofthe drawhead, is turned back slightly inits downward direction.l This is to prevent the pin being worked u-p bythe link drawing upon it.

I am aware thatthe pallet for holding the pin upis not'new; therefore, Ido not claim it.

Thiscar-couplingis particularly adapted to passenger-cars. A WhatI'desire" to secure by Letters Patent 1s 1. The -opening; a', when madeat an angle to the passage a,as shown, to receive the coupling-pin and prevent its working up, as

. set forth.

2. The combination and arrangement of the drawlhead A, inclined passagesa and 1t/,pin c, shoulder c', cap e, rod or chain g, and the pivotedpallet d, all constructed and operating asherein described.
